The brake system power assist is provided by a hydro-
boost unit which shares fluid with the power steering
system. You may experience some clicking or hissing
noises from the hydro-boost system during hard braking
conditions.
NOTE: Under cold temperatures, pedal effort will be
higher than normal until the power steering oil reaches
operating temperature.
Brake Noise
During normal operation of the brake system certain
noises may be present from time to time. Occasional
ЉgroanЉ or ЉsquealЉ noises may occur during normal
operation of the brake system which may not be indica-
tive of a problem. These noises may be heard at any time
the brakes are applied but may be more noticeable during
the first few brake applications in the morning. Moisture,
hot or cold temperature, dust, and or other debris may
also contribute to the noise condition. Repeated or con-
tinuous noises during braking may be an indication that
the brake linings are worn and in need of replacement.
Rear Wheel Anti-Lock Brake System — RWAL
The Anti-lock Brake System provides increased vehicle
stability and brake performance under most braking
conditions. The system automatically controls the opera-
tion of the rear brakes to prevent rear wheel lockup.
The system remains operational in the four-wheel drive
mode. The level of performance is reduced when the
front brakes are locked up. This may cause the rear
brakes to lockup through the drivetrain, which may
reduce the effectiveness of the Anti-lock Brake System.
During severe braking conditions, particularly with
changing road surfaces, such as ice to concrete, a slight
drop or minor pulsation may be felt in the brake pedal.
